#  Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8
#         with gcc-gfortran v4.3.x as shipped with Fedora Core 9,10

# OpenMP : Tested on dickens with gcc-gfortran v4.3.2 as shipped with FC 10
#          and on baudelaire with gcc-gfortran v4.4.5 as shipped with FC 13
#          also on danton    with gcc-gfortran v4.5.1 as shipped with FC 14
#-------
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS
#    and generally, needs to increase the thread stack-size:
#   -  sh,bash:
#     > export OMP_NUM_THREADS=2
#     > export GOMP_STACKSIZE=400m
#   - csh,tcsh:
#     > setenv OMP_NUM_THREADS 2
